Kindle Comic Converter Online, KCC in Your Browser

Kindle Comic Converter (KCC) is the community-standard tool for preparing manga and comics for e-readers, and MangaConverter runs the real thing for you in the cloud. Same processing pipeline, same device profiles, same output quality, without installing Python, hunting DLLs or driving a command line.

Drop a CBZ, CBR, ZIP, RAR, 7Z or PDF in your browser, pick the same profiles you know from KCC (from the Kindle 1 to the Colorsoft and Scribe, every Kobo, reMarkable), preview each page, and download MOBI, EPUB, KEPUB or CBZ.

How to use KCC online

  1. Drop your file No setup step, open the converter and drag your archive in. Batch several volumes if you want; they queue automatically.
  2. Pick a device profile The full KCC profile list is here: every Kindle, Kobo and reMarkable generation with its true resolution, plus format-only presets (EPUB, CBZ) and custom dimensions.
  3. Tune with live preview Manga mode, webtoon mode, spread handling, borders, upscaling, gamma, the familiar KCC options, but with a page-by-page preview rendered before you convert, so no more convert-check-repeat loops.
  4. Convert and download The conversion runs on our servers and your file is ready in minutes, download it and transfer to your reader. Files auto-delete after 24 hours.

Credit where due

KCC is a free open-source project. If the desktop workflow suits you, download it from the official KCC GitHub repository, MangaConverter is an independent hosted frontend for the same engine, not a replacement for the project.

What the desktop app still does better

Exotic edge cases, custom scripts, unusual output tweaks, offline conversion of huge libraries, remain desktop territory. For the everyday convert-and-read loop, the online version is faster to reach.

MangaConverter is powered by the genuine Kindle Comic Converter engine, kept up to date with upstream. Honest by design: we name the engine, respect its license, and add the hosting, preview and queueing around it.

Frequently asked questions

Is this really KCC, or a clone?

It is the real, unmodified KCC engine (open-source, by Ciromattia and the KCC contributors) executed on our infrastructure. We say so openly, the output is byte-for-byte the kind of file the desktop app gives you.

Why use the online version instead of the desktop app?

No Python environment, no install, works on any OS including tablets and Chromebooks, adds a live page preview, and batches queue in the background. If you love the desktop app, keep it, this is the same engine for when you are not at your own machine, or want zero setup.

Which KCC options are available?

The ones that matter for manga and comics: manga (right-to-left) mode, webtoon mode, spread handling and shifting, border trimming, upscaling, stretch, gamma/contrast controls, two-panel view and more, all with preview.

What formats go in and out?

In: CBZ, CBR, CB7, ZIP, RAR, 7Z, PDF, EPUB. Out: MOBI (Kindle profiles), EPUB, KEPUB (Kobo profiles) or CBZ. The profile picks the sensible default; you can override it.

Does it cost anything?

The free tier covers several conversions per month. Heavy users can upgrade, that is what pays for the servers the conversions run on.
